T0 all m1700771/ it Tranny concern.:

Be it known that I, SALEM E. KIEROLF, a citizen of the United States, residing at Jackson, in the county of Madison and State of Tennessee, have invented certain new and useful Improvements in Pea-Harvesters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the Same.

My invention relates to certain improvements in what are termed pea pickers or harvesters, while it is equally adapted as a clover-blossom harvester and for like purposes. In use it is effective for the intended purposes, expeditious in operation, sim plein construction, and inexpensive.

It consists of the combination and arrangement of the parts, including their construction, substantially as hereinafter more fully disclosed, and specifically pointed out by the claims.

Latitude is allowed herein as to certain details, as they may be changed at pleasure wit-hout departing from the spirit of my invention and the same yet remain intact and be protected.

In the accompanying drawings, Figure l is a plan view of a machine embodying my invention. Fig. 2 is a side view. Fig. 3 is a Sectional elevation taken on the line a: of Fig. 1. Fig. 4 is a detailed sectional view showing the pea-harvesting cylinder arm ed with additional blades, adapting it more particularly for harvesting cloverblossoms. Fig. 5 is an enlarged broken detailed view showing more especially the smaller or righthand traveling wheel and axle. Fig. G is a similar view showing more particularly the belttightening device or slide, presently fully described. Fig. 7 is a detached perspective view of a blade to substitute the relievingroll when the machine is used for harvesting clover-blossoms.

In carrying out my invention I provide a suitable frame 1, mounted, preferably, after the fashion of a grain dropper or harvester and provided with a stub-tongue 2. The double-cranked axle or shaft 3 of the transporting or carrying wheels 4 4., one (43) a masterwheel, has fixed on it under the platform or 'frame a driving sprocketwheel 5, having a half-clutch G, preferably of four teeth or pins, adapted to engage the spokes of the driving or master wheel 4 to suitably transmit motion to said sprocket-wheel. The axle I 3 has one end portion bent downward and then extended or terminated into the axlearm proper, 3, carrying the wheel 4, and bearing in the lower end of a bent axle-scction 3b, suitably held in a boxing or cap 3C, secured to the machine-frame, said axle-arm vhaving its terminal preferably held in the lower end of said axle-section bya nut 3d, all as seen in Fig. 3. This construction provides for the inequality between the master or main driving wheel Il and the small wheel 4 for the ready removal of said small wheel and for readily turning the machine. It is also 0bserved that the main axlesecton is secured- 7o rigidly to the stub-tongue, while the frame of the machine hangs from said axle-section, thus allowing said frame to be readilylowered and raised bysuitable means, aS will be presently made apparent.

The stub-tongue 2 iS adapted to be raised or lowered by the usual spring pawl and ratchet armed lever 7. The lever 7 is pivoted at its lower end upon the stub-tongue, as at 7, its pawl 7b engaging the ratchet or rack 7C, secured to the stub-tongue. Said lever is connected by a link 7d with a bell-crank 7X, pivoted at its angle or elbow to the stub-tongue 2, said elbow or bell-crank being linked, as at 7XX, to a lateral .arm of an angle-bracket a, preferablysecured to a lail-cylinder-supporting upright, presently referred to. The link 7XX is suitably held in place by a pin Z7, passed through apertures in the bent terminals thereof, preferably as shown. This arrangement provides for the ready tilting or raising and lowering, as occasion may require, of the forward end of the machine. The tongue 7e proper is detachably connected to said stubtongue, preferably by keepers or stirrups 7f 7g, attached to said stub-tongue and tongue proper, respectively, to provide for the removal of the tongue proper with the Whifiletrees, as preferably desired, as will be readily appreciated. A motion-transmitting chain belt 8, engaging and driven by the sprocketwheel 5, also engages a sprocket wheel or pulley 9 on a shaft 10, suitably hung on the frame or platform l, encompassed by and driving an endless apron or elevator 1l. This elevator also encompasses at its upper end a second shaft 12, suitably hung in upward and rearward inclined supports 13 to properly deliver the peas or other harvested crop, said supports being. secured at their lower ends to the frame 1. The chain belt 8 is next caused to engage a sprocket-pulley 14 on one end of the shaft 15, suitably hung in uprights 16, upon whose opposite end is a second sprocket-pulley 17, engaged by an endless chain belt 18, also engaging a second sprocket-pulley 19, carried by the shaft 20, hung in the frame 1 and carryinga cylinder 21,armed with slightly spiral or oblique blades or llails 21 and arranged above said frame or platform, said cylinder-shaft also passing through the uprights 16. The oblique or spiral blades or fiails 212L are formed integrally with the cylinder, their spirality or Obliquity extending in the direction of the length or longitudinally of the cylinder, while they taper radially or transversely outward, and intermediately of said blades or liails the surface of said cylinder is concaved, thus providing a series of concavities or spaces therebetween, as more clearly disclosed by Fig. 3, for the purpose hereinafter indicated. The chain 18 has connected to it one end of a slack compensating or tightening device or slide 18, having an elongated slot therein engaged by a holding or adjusting screw 18D,with its nut 1Sc adapted to engage said slide, the operation of which is obvious. Said chain belt 8 is further caused to engage and drive a sprocket-pulley 22 on one end of the relieving-roller 23, hung in the forward end of the frame or platform 1, providing a rolling bearing or surface at this point for the vines as they contact there` with when engaged by the flails or blades of the cylinder 21, turning toward said frame or platform in harvesting the peas, dac. The rolling bearing or roll 23 and the ail-cyl inder 21 turning counter-clockwise, (shown in Fig. 3,) said roll is caused to aid the passing of the vines relieved of their pods by the flails or blades under the machine out of the way, as will be readily understood. This roll or bearing also relieves the machine of the additional draft or resistance which would otherwise be exerted thereon; also, aids the discharge of the vines after the pea-pods have been flailed therefrom. The intermediate concaved spaces 24 between the flails or blades 21fL of the cylinder serve to prevent the pea-pods rolling olf the cylinder as they are detached from the vines nntil their proper delivery upon the apron or elevator l1, finally delivering said pea-pods from the machine. The chain or belt 8, being endless, passes from the sprocket-pulley 22 back to and continues to engage the sprocket-wheel 5, and so on.

A presser-plate 22a, having its upper surface curved to conform to an arc of the general circle described by the rotation of the cylinder 21 and having its forward edge portion 22b extending a suitable distance down opposite the corresponding edge of the platform or frame of the machine, is arranged directly under said cylinder and has secured to its under side at proper intervals apart approximatelysemi-elliptic orbowed springs 22, resting upon said frame to effect the holding 0f said presser-plate normally about an eighth of an inch from the path described by the blades or lails of said cylinder. The purpose of said presser-plate is to provide for relieving the vines as the cylinder ails or blades are removing or detaching the pods therefrom, and thus prevent the breaking of the vines, as would otherwise be liable to occur. The presser-plate 22n is itself held in place by suitable means-as, for instance, screw-bolts 22d, engaging the frame and passing through slots in said plate, with their outer headed ends adapted to serve as stops to limit the outward movement of said plate under the action of the springs 22c to the above-stated predetermined point. Said presser-plate has attached to its upper rear edge an apron or extension 22f, resting at its upper free edge upon the elevator or apron 11, to conduct the pea-pods to and provide for the ready elevation of said pea-pods therefrom by said ele- Vator.

A preferably downward curved guard or shield 22g, having one edge hinged to the rear edge of the forward cross-bar of the machineframe and its opposite edge retained by a button or catch 22, pivoted to the under side of said frame, is arranged just beneath or opposite t'ne lower end of the apron or elevator 11 to prevent interference therewith of the vines, duc. Its hinge connection with said cross-bar permits the swinging thereof downward to allow of the removal or dumping of any peas, dac., falling the-rein.

A lever 30, suitably fulcru med to the frame or platform by a bracket 30a, provides for shipping the driving-belt clutch mechanism.

A forwardly deflected or inclined fender or guard 3l is applied to the stub-tongue 2, its inneredge having secured thereto a keeper or stirrup 31a, fitted and suitably held upon said stub-tongue, said guard or shield being arranged in alinement with the power-transmitting chain 18 to prevent the interference therewith of the vines, duc.

Also applied to the forward end of the machine-frame at its right-hand side is a deiiector or divider 32 with its outer surface inn clined outward and rearward to laterally deflect the vines not in the direct path of the machine and which are to be engaged by the nailing-cylinder, which would otherwise intercept the proper operation of the machine.

It will be noticed that the bottom elevator or apron shaft has two fixed sprocket-wheels 26, one near each end, and the upper shaft thereof has similar idle sprocket-wheels 27a, as shown, which are fixed by nuts. The elevator-apronvitself is also suitably equipped with cups 28L or other suitable means to aid IOO IXO

the same to carry or elevate the pea-pods or blossom-seeds delivered thereon. Said cups or eqnipmentsvare preferably angular, with one arm of the angle secured in any suitable way to the apron or elevator.

For harvesting clover-blossoms I suitably provide for attaching to the fiailing blades or ribs 2l of the cylinder 2l a corresponding number of additional blades 27 and substitute for the relieving-roll 23 a xed blade 28, adapted to coact with said additional blades, said fixed blade being suitably secured or fastened at the forward edge of the machine, all as shown in Fig. 4, for the purpose as aforesaid.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Ina machine of the character described, the nailing-cylinder having a series of peripheral blades or iiails, and a roll arranged at the forward edge of the machine, both said cylinder and roll having their upper surfaces turning forward,and said cylinder lying above the passage of the objects acted upon,and said roll lying below said passage, substantially as set forth.
